To 6-[4-(5-Cyclopropyl-2H-pyrazol-3-ylamino)-6-iodo-quinazolin-2-ylamino]-1,2-dihydro-indazol-3-one (300 mg, 0.48 mmol), and phenyl boronic acid (88 mg, 0.72 mmol) in DMSO and 1.5 M potassium phenolate (2.6 mL) was added PdCl2 (dppf)2 (175 mg) and the solution was heated to 100° C. in a sealed tube. After 12 hr, the solution was diluted with water, extracted with ethyl acetate, dried (Na2SO4) and concentrated. The title compound was isolated by preparative HPLC as a white solid (0.82 mg). HPLC tr=5.14 min (10% to 90% MeCN over 8 min, total time 12 min, 3×150 mm C18 column) FIA m/e 475.55 (M+H), 473.55 (M-H).
